Description

Technical Field

[0001] This utility model belongs to the field of optical fiber cutting and processing technology, and specifically relates to an optical fiber jumper cutting limiting tool. Background Technology

[0002] A patch cord is a fiber optic connector with fiber optic connectors at both ends. It is used for flexible patching of optical paths between devices such as fiber optic distribution frames and fiber optic junction boxes, thereby enabling connections between different fiber optic links. Before splicing the patch cord to the optical cable, a fiber optic cleaver is used to cut the fiber core at the end of the patch cord to ensure a clean cut. The cleaver also has corresponding limiting fixtures to fix the patch cord in place, making the cutting operation easier. Current fiber optic patch cord cutting methods involve manual cutting by a worker. This method, lacking limiting fixtures, makes it difficult to keep the fiber optic patch cord in the predetermined position during cutting, resulting in low cutting accuracy.

[0003] To address this, a fiber optic pigtail cutting and positioning fixture, with publication number "CN217046083U", includes a base. The base has a first positioning groove for limiting the jumper connector of the fiber optic pigtail and a second positioning groove for limiting the optical cable of the fiber optic pigtail. The two side walls of the first positioning groove are respectively provided with a first recess and a second recess, which match the flange of the metal part of the jumper connector. This fiber optic pigtail cutting and positioning fixture, through the setting of the first and second positioning grooves, can limit the fiber optic pigtail during the cutting of the optical cable, keeping the fiber optic pigtail in a predetermined position, facilitating the cutting of the fiber optic pigtail by the operator and improving cutting accuracy.

[0004] However, for the aforementioned fiber optic pigtail cutting and positioning fixture, although the pigtail is placed in the V-groove on the fixture and then the clamping cover is closed to secure the pigtail in the V-groove, the following obvious defects still exist during use: Since the pigtails are usually stored in a coil like most optical cables, when clamped, the pigtails are prone to some displacement under bending stress, which causes the adjusted fiber core position of the pigtail to be disordered. The staff needs to straighten the pigtails and then reposition them, which affects the cutting work. Utility Model Content

[0005] The purpose of this invention is to provide a fiber optic jumper cutting and limiting fixture to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a fiber optic jumper cutting and limiting fixture, comprising:

[0007] The tooling base plate has a cutting limiting seat A on one side of the center position of the end of the tooling base plate for limiting and positioning one end of the optical fiber jumper. The cutting limiting seat A has a movable forming ring A with a groove on both sides of the center position of the end of the cutting limiting seat A, which limits and shapes one end of the optical fiber jumper. The tooling base plate has a cutting support seat on the corresponding side for supporting and positioning the optical fiber jumper during cutting. The cutting support seat has a cutting limiting seat B on the corresponding side for limiting and positioning the other end of the optical fiber jumper. The cutting limiting seat B has a movable forming ring B with a groove on the corresponding side of the end of the cutting limiting seat B, which limits and shapes the other end of the optical fiber jumper.

[0008] The rotating rod rotates from the outside of the cutting limit seat A to the inside of one end of the cutting limit seat B. The rotating rod is provided with rotating teeth at equal intervals in the cutting limit seat A and the cutting limit seat B to drive the circumferential movement of the fiber jumper movable shaping ring A and the fiber jumper movable shaping ring B to shape and limit the two ends of the fiber jumper.

[0009] Preferably, a positioning groove is provided at the center of the ends of the cutting limiting seat A and the cutting limiting seat B. The positioning groove can make the optical fiber jumper be in a relatively fixed position at the beginning of placement, reducing the workload of subsequent adjustments.

[0010] Preferably, the cutting limiting seat A and the cutting limiting seat B are uniformly provided with semi-circular cavities that pass through the center, and the slots at both ends of the semi-circular cavity are located on both sides of the limiting groove. Under bending stress, they are prone to displacement. The cooperation between the semi-circular cavity and the fiber jumper movable shaping ring can provide more stable shaping and limiting of the fiber jumper from both sides.

[0011] Preferably, a movable cavity is provided at the slot of one end of the semicircular cavity on one side of the cutting limiting seat A and the cutting limiting seat B, so that the rotating teeth can rotate inside. The slot at one end of the semicircular cavity is connected to the movable cavity. Through the meshing of the rotating teeth and the driving teeth, the precise control of the fiber jumper movable shaping ring is realized, ensuring that the two ends of the fiber jumper can be stably shaped and limited, and avoiding the impact of positional deviation on the cutting accuracy.

[0012] Preferably, the outer side of the cutting limiting seat A and the cutting limiting seat B are respectively provided with positioning covers A and B via hinges, which are used to limit and shape the two ends of the optical fiber jumper and then close them. Each of the positioning covers A and B has a movable pressing groove at a position corresponding to the limiting groove, and rubber pressing blocks are equidistantly arranged in each pressing groove. The inner side of the pressing groove has a groove that allows the movable shaping rings A and B of the jumper to rotate and be pressed together. The rubber pressing blocks increase the friction with the optical fiber jumper, preventing it from sliding during the cutting process. Simultaneously, the cooperation between the pressing groove and the movable shaping rings allows the positioning covers to further stabilize the optical fiber jumper after the shaping rings have shaped it.

[0013] Preferably, the movable shaping ring A and movable shaping ring B of the fiber jumper are movably disposed inside the semi-circular cavity, and the movable shaping ring A and movable shaping ring B of the fiber jumper are uniformly provided with driving teeth on their outer surfaces. The driving teeth mesh with the rotating teeth rotating inside the movable cavity, which can conveniently drive the movable shaping ring A and movable shaping ring B of the fiber jumper to move in a circular motion, thereby shaping and limiting the two ends of the fiber jumper.

[0014] Preferably, the rotating rod has an auxiliary rod at one end outside the cutting limit seat A, and a rotating handle with a threaded surface at one end is provided at one end of the auxiliary rod. The rotating handle is provided with an internal thread locking groove in a circular shape at one end of the surface of the cutting limit seat A, which locks the rotating handle at one end inward and positions the rotating rod. This ensures the shaping and limiting effect of the fiber jumper ring on the fiber jumper and avoids the fiber jumper position from changing due to loosening of the rotating rod during the cutting process.

[0015] Preferably, the cutting groove at the end of the cutting support seat extends to one side and has an open cutting groove. A magnetic strip is embedded on one side of the ends of the cutting limiting seat A and the cutting limiting seat B, so that the positioning cover A and the positioning cover B are magnetically fixed after being closed, to prevent the positioning cover from being accidentally opened during the cutting process and to ensure the smooth progress of the cutting work.

[0016] Compared with existing technologies, the technical effects and advantages of this utility model are as follows: This fiber optic patch cord cutting and limiting fixture, through the limiting grooves at the ends of the cutting limiting seats A and B, allows the fiber optic patch cord to be accurately positioned in the initial placement stage, greatly reducing subsequent adjustment work caused by improper initial placement. Simultaneously, the cooperation between the semi-circular cavity and the movable shaping rings A and B of the patch cord overcomes the problem of displacement caused by bending stress in the pigtail, providing stable shaping and limiting of the fiber optic patch cord from both sides. This ensures that even under the influence of its own stress and other factors during the cutting process, the fiber optic patch cord remains stable and unaffected, guaranteeing that the cutting accuracy is not compromised.

[0017] The engaging structure of the movable cavity with rotating and driving teeth provides operators with precise control over the fiber optic patch cord's positioning ring. This allows for flexible adjustment based on the actual condition of the fiber optic patch cord, achieving precise positioning and limiting at both ends. The positioning caps A and B, along with their internal rubber pressure blocks and pressing grooves, further enhance the fixing effect, preventing the fiber optic patch cord from slipping during cutting. The auxiliary rod, rotating handle, and internal threaded locking groove on the rotating rod facilitate operation and prevent loosening, ensuring effective positioning and limiting.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-4 This utility model provides a technical solution: a fiber optic jumper cutting and limiting fixture, comprising:

[0025] The fixture base plate 1 has a cutting and positioning seat A2 at one end center position for limiting and positioning one end of the optical fiber patch cord. A limiting groove 9 is formed at the end center position of the cutting and positioning seat A2 to cooperate with a positioning cover A10. When the positioning cover A10 is closed, it can better limit and fix one end of the optical fiber patch cord. On both sides of the end center position of the cutting and positioning seat A2, there are movable patch cord shaping rings A3, which are annular and have grooves, for positioning and limiting one end of the optical fiber patch cord. The movable patch cord shaping rings A3 are located inside a semi-circular cavity 11, which provides them with space for movement. Simultaneously, the semi-circular cavity 11 restricts their movement, ensuring they can only move circumferentially within a certain range. A corresponding side of the fixture base plate 1 has a [missing information - likely a feature related to optical fiber patch cord positioning]. The cutting support seat 4, which supports and positions the fiber optic jumper during cutting, is installed on the corresponding side of the tooling base plate 1 and is on the same axis as the cutting limit seat A2 and the cutting limit seat B5. It provides support for the fiber optic jumper during cutting. The corresponding side of the cutting support seat 4 is provided with a cutting limit seat B5 for limiting and positioning the other end of the fiber optic jumper. The cutting limit seat B5 is opposite to the cutting limit seat A2 and is set on the other side of the tooling base plate 1. Its internal structure and connection method are similar to those of the cutting limit seat A2. The cutting limit seat B5 has a movable and equidistant ring B6 at the end, which is a circular ring with a groove for positioning and limiting the other end of the fiber optic jumper. When the positioning cover B13 is closed, part of it can enter the positioning groove 20 of the positioning cover B13 for pressing and positioning.

[0026] A rotating rod 7 rotates from the outside of the cutting limit seat A2 and passes through to the inside of one end of the cutting limit seat B5. The rotation of the rotating rod 7 drives the rotating teeth 8 to rotate, thereby driving the movable shaper rings A3 and B6 of the fiber jumper to move circumferentially. The end located outside the cutting limit seat A2 is connected to an auxiliary rod 17. The upper limit of the auxiliary rod 17 is connected to a rotating handle 18. One end of the rotating handle 18 can be connected to the surface of the cutting limit seat A2 through an internal threaded locking groove 19 to position the rotating rod 7. The rotating rod 7 is provided with rotating teeth 8 at equal intervals in the cutting limit seat A2 and the cutting limit seat B5 to engage and drive the movable shaper rings A3 and B6 of the fiber jumper to move circumferentially and shape and limit the two ends of the fiber jumper. When the rotating rod 7 rotates, it drives the rotating teeth 8 to rotate, thereby driving the movable shaper rings A3 and B6 of the fiber jumper to move circumferentially.

[0027] A limiting groove 9 is provided at the center of the end of the cutting limiting seat A2 and the cutting limiting seat B5. The limiting groove 9 is provided at the center of the end of the cutting limiting seat A2 and the cutting limiting seat B5, and corresponds to the movable pressing groove 14 on the positioning cover A10 and the positioning cover B13. When the positioning cover A10 and the positioning cover B13 are closed, the two together limit the fiber jumper.

[0028] The cutting limit seat A2 and the cutting limit seat B5 are evenly provided with semi-circular cavities 11 that are semi-circular through the end. The slots at both ends of the semi-circular cavity 11 are located on both sides of the limiting groove 9. This provides space for the movement of the fiber skipping movable shaping ring B6 and the rotation of the rotating tooth 8. A movable cavity 12 is opened at one end of the slot of the semi-circular cavity 11 on one side to allow the rotating tooth 8 to rotate.

[0029] A movable cavity 12 is provided at one end of the groove of the semicircular cavity 11 on one side of the cutting limit seat A2 and the cutting limit seat B5, so that the rotating tooth 8 can rotate inside. The groove at one end of the semicircular cavity 11 is connected to the movable cavity 12.

[0030] The outer sides of the cutting limiting seat A2 and the cutting limiting seat B5 are respectively provided with positioning covers A10 and B13 via hinges, which limit and shape both ends of the fiber optic jumper and then close them. The positioning groove 20 presses the movable shaping ring of the jumper. Each of the positioning covers A10 and B13 has a movable pressing groove 14 at a position corresponding to the limiting groove 9. Rubber pressing blocks 15 are evenly spaced within each pressing groove 14, and the inner side of the pressing groove 14 is provided with a mechanism to allow the movable shaping ring A3 of the jumper to be closed. After the fiber optic movable shaping ring B6 rotates, it is pressed into the internal fixed groove 20. The positioning cover A10 and the positioning cover B13 have movable pressing grooves 14 at the positions corresponding to the limiting fixed groove 9. The movable pressing groove 14 is provided with a rubber lower pressure block 15 and the fixed groove 20. When the cover is closed, the rubber lower pressure block 15 can generate a certain downward pressure on the fiber optic jumper. When the positioning cover A10 and the positioning cover B13 are closed, the jumper movable shaping ring A3 and the jumper movable shaping ring B6 can rotate into the fixed groove 20.

[0031] The fiber skipping movable shaping ring A3 and the fiber skipping movable shaping ring B6 are movably disposed inside the semi-circular cavity 11, and the outer surfaces of the fiber skipping movable shaping ring A3 and the fiber skipping movable shaping ring B6 are uniformly provided with driving teeth 16, and the driving teeth 16 mesh with the rotating teeth 8 rotating inside the movable cavity 12.

[0032] An auxiliary rod 17 is provided at one end of the rotating rod 7 located outside the cutting limit seat A2. A rotating handle 18 with a threaded surface is provided at one end of the auxiliary rod 17. The rotating handle 18 is provided with an internal threaded locking groove 19 in a circular shape at the position of the rotating handle 18 on the surface of the cutting limit seat A2. This groove locks the rotating rod 7 by locking the rotating handle 18 in the internal thread. This provides a precise structural basis for locking the rotating rod 7 and ensures that the position of the rotating rod 7 is fixed after the shaping operation is completed. This prevents the shaping state of the optical fiber jumper from being affected by the rotation of the rotating rod 7 during the cutting process.

[0033] The cutting support 4 has a cutting groove at one end, which extends to one side to form an open cutting groove 21. The open cutting groove 21 provides space for the cutting operation, making it convenient for the cutting tool to cut the fiber jumper. A magnetic strip 22 is embedded on one side of the ends of the cutting limit seats A2 and B5, which magnetically fixes the positioning covers A10 and B13 after they are closed. The magnetic strip 22 is embedded on one side of the ends of the cutting limit seats A2 and B5 and has a magnetic attraction with the positioning covers A10 and B13. When the positioning covers A10 and B13 are closed, they provide magnetic fixing force.

[0034] Specifically, in use, one end of the fiber optic patch cord is placed in the slot of the movable shaping ring A3 of the cutting limit seat A2, and the other end is placed in the slot of the movable shaping ring B6 of the cutting limit seat B5. At this time, the fiber optic patch cord is located on the fixture base plate 1, and the cutting support seat 4 is located below the fiber optic patch cord to provide support. Rotating the rotating rod 7 causes the rotating teeth 8 inside the cutting limit seat A2 and the cutting limit seat B5 to rotate synchronously. Since the rotating teeth 8 mesh with the driving teeth 16 on the outside of the movable shaping rings A3 and B6, the rotation of the rotating teeth 8 drives the movable shaping rings A3 and B6 to move circumferentially within the semi-circular cavity 11, thereby shaping and limiting both ends of the fiber optic patch cord to achieve the required shape and position.

[0035] After rotation, the rotating handle 18 locks the rotating rod 7 through the internal threaded locking groove 19 to prevent it from rotating in subsequent operations. Next, the positioning covers A10 and B13 are rotated around the hinge and fitted onto the cutting limit seats A2 and B5, respectively. At this time, the movable pressing grooves 14 on the positioning covers A10 and B13 correspond to the limiting grooves 9 on the cutting limit seats A2 and B5, and the rubber pressure block 15 exerts downward pressure on the fiber optic jumper, further fixing the fiber optic jumper. Simultaneously, the jumper movable shaping rings A3 and B6 partially enter the fixing grooves 20 of the positioning covers A10 and B13, and are further pressed and positioned. Furthermore, the magnetic strip 22 magnetically attracts the positioning covers A10 and B13, enhancing the stability after the positioning covers are closed.

[0036] The fiber optic patch cord is precisely positioned and shaped. At this point, the fiber optic patch cord can be cut using a cutting tool through the opening slot 21 at the end of the cutting support 4, ensuring that the fiber optic patch cord will not shift during the cutting process and guaranteeing the accuracy and quality of the cutting.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
